CALL-R-EGISTERING TEL'PHONE.

Specification of Letters Patent.

Patented Aug'. 11, 1914.

Application filed September 19, 1913. Serial No. 790,667.

To all whom it may concern Be it known that we, FENWICK D. FABER, JOI-IN TIBB, and JOHN WILFRED Tren, citizens of the Dominion ofCanada, residing `at Vancouver, in the Provinceof British Co-V lumbia, Canada, have invented cert-ain newl and useful. Improvements in Call-Register ing Telephones, of which the following is a specification. u

This invention relates to a telephone in- `strument having provision within itlor registering a call whenever the central operator connects the user to the phone with which he desires to speak, by which means the user of a phone may be charged strictly according to such use, instead of, as at present,`

paying a flat rate or on the basis of a record kept by the central operator and checked or not by the user.

The Invention' also comprises a provision whereby when a certain number of ycalls 1s exceeded the phone is automatically-discon-- nected from the telephone circuit andi cannot `be rei-connected except by a properly authorized person. n

j The phone is used in conjunction with a plug box which is permanently connected to the telephone circuit in which box is the actuating mechanism of the register and the means for transmitting the registering movement to the registering mechanism of the phone, which is removably connected to the plug boxwhenever the phone is to be used.

The invention is particularly described in the following specification, reterence'being made to the drawings by which it is accompanied, in which:

Figure 1 is a face View of the interior of the plug box, the cover being removed. Fig. 2 is a vertical section on the line A A of Fig. 1 through the plug box with the cover in position. Fig. 3 is a view of the telephone transmitter and receiver as connected together for` portability when not in use. Fig. 4 is a longitudinal section through the telephone transmitter and the automatic call register showing the protecting cap detached, and Fig. 5 is a cross section of the same on the line B in Fig. `4. U

In these drawings 2 represents aA call box which forms a permanent attachment in a room or building, to which box thewires 6 and `7 of the telephone system are connected at the terminals 4 and 5 and are conducted within the box. There is also a terminal 8 for the attachment of the grounding wire 9. Viithin the box 2 is an electromagnet 10,

the coil of which is in circuit between one of the terminals 4 of the telephone system and the terminal 8 of the ground wire 9. The armature 11 of this electromagnet is on the end ofone arm 12 of a bell crank lever 12--14 which is pivotally mounted at 13 on an attachment to the box 2, and this armaturell is normally held out of contact by a light springfl between one side of the box and the armature, which spring holds the armature against `a stop 17 projecting outward from the back of the box. The end of the shorter arm 14 of the bell crank is formed as a segment with teeth, which mesh with thoseon the outside of a plug socket member 15 which is rotatably mounted on suitable insulation wit-hin the box 2. The socket 18 of the member 15 is provided with driving serrations to engage and rotate a corresponding tapered plug of the telephone call register to be describedlater. The metal socket member 15 is electrically connected by a wire 19 to the terminal 4 of the telephone circuit.

The cover 8 of the call box vis furnished with an apertured socket 2O which is in axial alinement with the socket member 15 and on one side of this socket 20 is a Contact member 21 which is electrically connected by a wire 22 with the terminal 5 of the telephone circuit. j

The telephone transmitter 25 is mounted on one end of a hollow casing 26, the other end of `which casing is designed to tit the socket` 20 or' the call box cover 8. Rotaj tably mounted in the smaller end of this hollow casing 26 and supported in a suitably insulated end bearing 27 within it, is a stem 28., which `stem projects through the end and has secured on it a Contact plug 29 which is provided with longitudinal driving serrations corresponding with those ot the socket 18 of the socket member 15. `Within the casing 26 this stem 28 is threaded to receive an indicating nut 30 from which a pointer 31 projects into an elongated slot 82 .through the side` of the casing. `Secured on the stem 28 within the casing 26 is a ratchet `wheel 33the teeth of which are engaged by a small pawl 34 mountedon the end of the casing and having an end 35 projecting beyond its pivot, and adjacent to and the contact 21 within the socket of the box. The contact 21 should project within the circle of the end-of 26 which is inserted in 20 so that the contact itself will form a key to'insure that the telephone is in the correct position to insure contact.

Secured on suitable insulation on the cross bar V40, which supports the bearing Vplate 27 of the spindle 28, isa light resilient contact A41 which extends parallel with the axis Vof the stem 28 and exercisesVV a contact with the Y nut 30 as it travels along the screwed end of 28. This contact 41 is of such length that when the nut 30 has traveled to its extreme limit it will be free from engagement with the i contact.

The-'contacts '37 and- 41 are electrically connected with the transmitter 25 and its receiver 45, which parts may be removably' connected together by inwardly bent exten- Vsions 43 from the mouth plate of the transmitter.

In use. when the end of the telephone casing 26 is inserted in the aperture 20 of the call box'2 connection'is madebetween the terminals 4 and 5 of the telephone circuit through the telephone and its receiver by Contact of 37 with 21 and 29 with 15, and a call is given to the operator at the central otlice. The operator, in response to this call, connects the caller to the phone with which he desires to speak and by pressing a keyv or button at the central station closes the'fcircuit via wire Gand ground connection 9 to energizerthe magnet 10. Thus current passes through the lrelay 10 and itis energized and attracts its armature l1 to it and through the bell crank lever 12e-14 rotatablyoscillates the plug socket member 15. This partial rotation of 15 is communicated through the plug 29 and stem 28 and advances the indicating nut 30 a fractional distance along the screw, the pawl of the ratchet wheel holding the stem in. the position to which it is moved when the telephone is removed from the call box socket at the completion of the desired conversation. hen the'numberof calls have been made for which that particular phone has be endwise movable in or out Vby'Letters Patent, is:`

wardA to carry theindicating nut 30""to its starting'pointL 1 The pointer 31 of, the Anut indicates to the user the general number of calls recorded and the nearness to the outof-use limita. i

The telephone Vtransmitter and receiver mav be of any approved pattern *but will preferably be made small where they are required to vbe portable7 andfa guard cap 44V will be providedV to fit on the end of thetelephone casing 26 .to protect the projecting endof the stem 28a-and its plug 29 :fromV Y injury. l/Vherenot required to be portable as forgeneral ohce `use,"the telephone mayY e slidablv mounted onthe call box so "astor of the socket 20 of the `call box. 1 f Y Vith this arrangement oi 'automatically recording the phone calls, call boxes may be stationed in publicplaces-for the convenience of telephone users, so that any one having a phone of' ai portableform may insert it in the socket of any call" box and be connected by the central office to the phones with which they desire to speak.`

The Vgeneral use ofthese phoneswill not 'only be convenient for the users but will save the telephoneV companies a very considerableamount of expense ofcollectin'g accounts, as the cost of say five hundred calls is practically prepaid when a phone is -issuedwhich is good :torV that number. p Y
